RADIATOR.

Application filed April 19,

To all whom it may concern:

Be it known thatI, JOHN F. VIDLER, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented new and useful Improvements in Radiators, of which the following is'a specification.

This invention relates to improvements in radiators and the principal object of theinvention is to so construct the radiator that it will be light in weight, will not burst when frozen and will be flexible so that it can be easily bent to be placed against curved walls and the like. I

Another object of the invention is to make the walls of the radiator of a sheet of material bent into corrugated form and to provide a plurality of wedge-shaped members for forming the top and bottom of the radiator.

The invention also consists in certain other features of construction and in the combination and arrangement of the sev eral parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding partsthroughout the several views, and in which Figure 1 is a top View of a radiator constructed in accordance with my invention;

Fig. 2 is an end view;

Fig. 3 is a side View of a portion of a radiator;

' a. '.s a section on line 4-4 of Fig. 2; Fig. 5 is a section on line 55 of Fig. 1; Fig. 6 is a section-on line 66 of Fig. 3.

7 is a sectional view taken through some of the lower cap members. h

Fig. 8 is a plan View of one of the caps.

In these views 1 indicates the side members of the radiator which are composedof corrugated plates which provide the V- shaped projections and recesses, as shown in Fig. 4. If desired, the side members may be formed from a single strip or plate having its ends suitably welded together. The ends of the radiator are provided with the flat portions 2 and each flat portion is provided with an opening 3 to receive the connecting pipes. The top' and bottom of the radiator are closed by a plurality of cap members 8 which are of substantially wedge shape in cross section and the open ends of Specification of Letters Patent.

these caps are adapted to be welded to the top and bottom edges of the corrugated side plates with a cap engaging each of the V- shaped projections formed by said corrugatlons. Each cap is provided with a flat central lower edge portion which will abut against 'a like portion on the adjacent cap and these abutting portions are adapted to be secured together to prevent leakage at this point. Upper and lower pairs of rods 4 are passed through the radiator with their ends secured to the flat end portions and these rods support the parallel plates 5 which extend close to the top and bottom of said'radiator and act to set up a circulation of the water, as shown by the arrows in Fig. 6.

It will thus be seen that the radiators constructed as above described will be, very light and will be flexible so that they can be bent to fit in curved places. made of any size desired. By the corrugations in the plates and the caps a large heating surface is provided in the minimum amount of space.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is 1. A radiator of the class described com prising side members formed with vertically arranged corrugations and flat end members having rods passing longitudinally through the radiator and having their ends connected with the end plates and longitudinally extending baffle plates connected by said rods.

2. A radiator of the class described comprising side members formed with vertically arranged corrugations, wedge-shaped closing caps connected with the upper and lower edges of said members, said wedge-shaped caps having their central lower edge portions abutting each other and secured together.

3. A radiator of the class described comprising side members formed with V-shaped corrugations, wedge-shaped closing members connected with the upper and lower edges of said plates and parallel baffle plates located in the radiator.

In testimony whereof I alfix m JOHN F.
